CHURNING OR MIXING APPARATUS.

Patented May 30, 1911.

To all whom it may concern:

Be it known that I, HAROLD S. BROWN, a citizen of the United States, andresident of Stratford, Fairfield county, Connecticut, have made acertain new and useful Invention Relating to Churning or MixingApparatus, of which the following is a specification, taken inconnection with the accompanying drawings, which form part of the same.

This invention relates to churning or mixing apparatus and relatesespecially to small sized household devices of this character having aglass body.

In the illustrative embodiment of this invention shown in the drawings,Figure 1 is a vertical central section, Fig. 2 is a detail view showingsome of the part-sin disengaged position, Fig. 3 is a side elevation,parts being removed, Fig. 4 is a top sectional view along the line 44 ofFig. 1, Fig. 5 is a similar view through the body along the line 5-5 ofFig. 1, and Fig. 6 is a detail showing the cover attaching grips.

In the illustrative embodiment of this invention shown in the drawings,the body 1 may with advantage be formed of substantially transparentglass and be provided with various indications such as 47 for measuringthe various ingredients used. The operating parts are preferably mountedon the cover 23 which may be of sheet metal and formed with an outerdepending flange 40 overlapping the body and closing the same inconnection with a suitable washer 39 if desired, which may be moresecurely held in position by forming the cover with a coiiperatinginternal flange 60 within the body 1. The frame 21 carrying theoperating parts of the apparatus may be conveniently secured to thecover by suitable rivets 22 and the cover may be secured to the body byany desired means, such as an interrupted screw connection. Theinterrupted threads 41 may be formed on the body and it is desirable inthe case of such glass or other frangible bodies or containers to have ayieldable connection which minimizes strain and breakage. For thispurpose a series of suitable spring grips 42, 43, 44, 45, may be rivetedor otherwise attached to the cover 23 so as to be normally clear of thesame at its outer edge as indicated in Fig. 6. These grips are formedwith suitable thread engaging outer ends 46 so as to cotiperate with thescrew threads 41 on the body and yieldingly hold the cover down inengagement therewith. In this way the cover may be held on as securelyas desired by turnlng it to the desired extent after the grips engagethe screw threads and with such individually yielding grips, slightinequalities in the threads and cooperating parts do not cause suchundesirable strains in the container.

The frame 21, which may be of galvanized iron or other material, may beprovided with the hand grip 16 and the co6perating guard 15 which may beengaged by the user to firmly hold the apparatus in position while it isbeing operated. Other frame members 17, 18, 19, rigidly support variousbearings such as the journal 20 in which is mounted the drive shaft 34having the shoulder 35 and operating handle 36 integral therewith, ifdesired. This drive shaft may have the polygonal shank 33 integraltherewith so that the beveled driving gear 30 formed with a coiiperatingpolygonal hole may be readily secured to the drive shaft and firmly heldin position by the gear clip 31 coiiperating with a suitable recess 32in the shaft and held in the retaining position indicated in Figs. 1 and3 by the projection 52 on the gear with which the end 53 of this clipengages. This drive gear 30 may operate the dasher 2 provided withsuitable internally projecting dasher blades such as 3 and having thedasher shaft 26 engaging a suitable bearing 24 in the frame. The shank27 which may be integral with this dasher shaft may fit a cooperatingpolygonal hole in the dasher gear 28 which may be retained in positionon the shank by a suitable spring retaining ring 29 fitting within theshoulder 59 on the shank. If desired, also, a suitable dasher clip suchas 25 may be forced into the lateral recesses in the dasher shaft justabove the bearing 24 so as to hold the shaft and dasher firmly in oerative position and yet allow the ready dismounting of these parts whendesired.

If desired, a suitable internal dasher or paddle 5 may be used androvided with paddle blades 4 which may be of varying length and arrangedbetween the dasher blades 3 so asto give an increased churning or mixingaction. The paddle may be rotated in the opposite direction from thedasher by suitable gearing operated from the drive shaft. operates witha suitable bearing 8 in the lower part of the dasher and is provided atits upper end with the socket 6 wlth whlch the polygonal end 7 of thepaddle shaft 9 cooperates. This paddle shaft firmly holds the paddle inoperative position as long as its'end engages the socket in the paddlebut as soon-as the shaft is withdrawn, the paddle may be removed forcleaning or otherwise. Thehead 11 may be formed at the upper end of thispaddle shaft and may cooperate with a suitable bearing in the frame andhave, if desired, a bearing pivot 61 in its upper end which maycooperate with the paddle retainer 13 which as indicated in Fig. 3 issprung around the frame member 14 so as to slide longitudinally thereof.When 1n the position indicated in Figs. 1 and 3, this retainer holds thepaddle shaft down 1n operative position while when the retainer isslipped to one side as indicated 1n dotted lines in Fig. 2, theprojecting flange 12 of the head, may be engaged by the operator to pullup the paddle shaft as indicated 1n dotted lines. This paddle shaft mayif desired, be formed with the polygonal shank 1O cooperating with asimilar hole in the paddle gear 37 meshing with the drive gear 30. Insome cases, also, it is desirable to more permanently secure this gear37 to its shaft and for thisv purpose the pin 38 may be passed throughthese two parts to firmly connect them.-

From the foregoing description, it is evident that this apparatus mayafter shipment be readily assembled by an unskilled person and may bereadily taken apart at any time as for cleaning. Under operatingconditions, when the cream or other material has been placed in the bodyor container the cover and connected operating parts may be readilysecured thereto by the interrupted screw connections described and thenthe operator by turning the handle may effect an energetic churning ormixing action by the oppositely revolving dasher and paddle havingintermeshing blades. The operation may be readily observed through theglass container and if desired, material may be added from time to timeduring the operation through the opening 48 in the cover which isnormally closed by the cap 49 shown in Fig. i as secured by the pivot 51about which it may be swung by the upstanding handle or lug 50. It is ofcourse highly advantageous to have the body or container of suchapparatus formed of glass because of the facility with which it can bekept clean, aside from the other desirable features mentioned and it isalso highly desirable to As indicated, the paddle cohave the dasher andpaddle entirely supported from the cover so that they operate withoutthe necessity of anybearing formed in the body or container itself.

Having described this invention in connection with an illustrativeembodiment thereof, to the details of which disclosure the invention isnot of course to be limited, what is claimed as new and what is desiredto be secured by Letters Patent is set forth in the appended claims. I
